I bought a NAS drive a year or two ago and I was trying to upgrade the firmware to the latest version, 1.60. Unfortunately along the way the firmware update managed to fail and I ended up with a bricked NAS. The result was a RED LED light blinking at me six times in a row upon reboot requiring. I tried quite a few combinations before I was able to restore anything. I’m writing them out here, step by step, just in case it helps someone.
